Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621308, here are decompositions:

71 + 8621237 = 8621308
107 + 8621201 = 8621308
257 + 8621051 = 8621308
359 + 8620949 = 8621308
461 + 8620847 = 8621308
467 + 8620841 = 8621308
569 + 8620739 = 8621308
587 + 8620721 = 8621308

Showing the first eight; more decompositions exist.
